NOVEL BABY JUMPER Filed May 25, 1961 INVENTOR DANIEL BERLIN ATTORNEYS 3,0663% NOVEL BABY JUMPER Daniel Berlin, 4424 Paul St, Philadelphia 24, Pa. Filed May 23, 1961, Ser. No. 111,984 4 Claims. {CL 248-399) This invention relates to an exercising seat for babies, also known as a baby jumper, and particularly to a baby jumper that is foldable. This application is a continuation-in-part of my copending application Serial No. 53,108, filed August 31, 1960.

A baby jumper is often constructed with a sling seat of canvas or the like and a frame that is spring mounted to provide a safe support for the seat and to permit and encourage jumping and exercising by a baby user. At the same time, the baby jumper should exhibit a higher degree of stability to ensure the safety of the baby.

It is therefore an object of this invention to provide a novel baby jumper.

It is another object of this invention to provide a novel baby jumper that is safe and reliable.

It is a further object of this invention to provide a novel baby jumper that is easily collapsed and can be folded compactly.

It is a further object of this invention to provide a novel collapsible baby jumper that is reasonable in cost of construction.

In accordance with this invention, a baby jumper includes a seat frame fora sling seat, a base for resting on the floor and a spring urged linkage for connecting the 9 seat frame to the base. The linkage includes two pairs of pivoted links, means pivotally connecting the pairs of links to opposite sides of the seat frame and base, while permitting pivoting of the links at the seat frame and base, and a pair of disengageable spring biasing means, each respectively connecting a link of one pair of said links to said base to permit folding of the unit when said means is disengaged.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is a perspective view of a baby jumper em bodying this invention;

FIG. 2 is an enlarged sectional view along the line 22 of FIG. 1 illustrating the spring biasing means and a removable pin connector;

FIG. 3 is a view similar to FIG. 2, but with the pin in its released position;

FIG. 4 is an enlarged sectional view along line 4-4 of FIG. 1 illustrating the removable pin connector;

FIG. 5 is a side elevational view of the baby jumper of FIG. 1 on a reduced scale, but placed in a folded condition; and

FIG. 6 is an enlarged Sectional view along line 66 of FIG. 1.

In the drawing, corresponding parts are referenced by the same numerals.

A baby jumper includes a sling seat ll) of fabric or the like having tubular arm portions 12 that receive the legs 14 of a U-shaped tubular seat frame 16. A plastic tray 18 is attached to the cross-portion of the U-frame 16. Pivoted to the free ends of the legs 14 is a generally U-shaped wire frame 20 that frames the back 22 of the sling seat 10. As shown in greater detail in FIG. 6, legs 14 include a hooked portion 24 to limit the backward movement of frame 20, and thereby set the angle of back 22.

A U-shaped tubular base 26 having legs 27 is used to support the seat. A pair of generally parallel tubular rCe bar links 28 are pivotally attached to lower legs 27 by means of pins 34 and to upper legs 14- by means of shaft 32. Shaft 32 also serves the function of supporting the front portion 84 of sling seat 10. If desired, beads 36 can be placed on shaft 32.

A second pair of generally parallel tubular bar links 39 are pivotally connected to lower legs 27 by pins 38 and to upper legs 14, by flanged extensions it) of frame 2%. Extensions 40 are capped at 42 to secure legs 39 in place.

The disengageable spring biasing means is shown generally at A. This means comprises tension springs 46 pivotally anchored to lower legs 27 by pins 38. Fixed stabilizing bars 48 are connected to springs 46 by pins 56. A second set of stabilizing bars 52, which are releasably slidable with respect to bars 4-8 and having holes 54 therein, are pivotally connected at said holes 54 to links 28 by pins 55 projecting through said holes. The stabilizer bar 52 is slidingly engaged in U-shaped bracket 56 having flanges 58 extending at right angles from the free ends 59 thereof. Slidingly engaged in bracket 56 and perpendicular to the stabilizer bars 48 and 52 is pin 60'. The head of pin \50 is spaced from bracket 56 by cylinder 62 welded on the bracket. Pin 60 is urged into bracket 5'6 by means of tension spring 64- coiied thereabout. Bars 48 and 52 have lateral holes 66 and 68, rmpectively, adapted to receive pin 6%).

The folded condition of the jumper is shown in FIG. 5. To place the jumper in operating condition, the back 22 is pulled up until hole 68 in bar 52 is aligned with the shaft of pin 66. The pin 61 will automatically slide into the hole under the urging of spring 64, as shown in FIG. 2. The jumper will then be in the operating condition illustrated in FIG. 1.

To collapse the jumper, pin 69 is removed from hole 68 by pulling pin 60 outwardly in the direction of th arrow 70 of FIG. 4 against the pressure of spring 64.

Bar 52 is then slid in the direction of arrow '72 with respect to bar 52, as shown in FIG. 3. The links 23 and 39 are now free to pivot into the plane of base 26 in the direction of arrow 74 of FIG. 1. Folding is completed by similarly moving wire frame 29.

Various safety and convenience features may be added to the jumper. For instance, plastic gliders 76 (FIG.l) may be placed under base 26. Also, caps may be placed on the open ends of all tubular parts, as at 73 (FIG. 1).

In use, the seat is depressed somewhat by the weight of the baby. The jumping action of the baby up and down is partially tmanslated into forward and backward movement and is followed by the seat it under the urging of the springs 46. The longer length of curved links 39 creates a permanent forward movement which prevents the jumper from tilting backwardly during use. Folding and unfolding the jumper is easily accomplished due to the ease of disengaging bar 52.

Obviously, many modifications and variations of the present invention are possible in the light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.

What is claimed as the invention is:

l. A baby jumper comprising a seat frame, a substantially horizontal base for supporting said seat frame, a linkage for connecting said seat frame to said base, said linkage including two pairs of pivoted links, means pivotally connecting the pairs of links to opposite sides of said seat frame and said base, all of said pivotal connecting means on said base being in the same horizontal plane, a first pair of reinforcing bars pivotally connected to one pair of links, a second pair of reinforcing bars slidingly engaging said first pair of reinforcing bars, brackets partially surrounding and engaging both pair of bars, alignable holes in both pairs of bars and said brackets, releasable means keeping said holes in alignment, and resilient means pivotally securing said second pair of reinforcing bars to said base, whereby said seat frame is free to resiliently pivot around said links. 5

2. The baby jumper of claim 1 wherein said means for keeping said holes in alignment are pins.

3. The baby jumper of claim 2 wherein said pins are spring urged into said holes.

4. The baby jumper of claim 1 wherein said resilient 10 securing means include a coil spring. 1
